LOOSE-LEAF BINDER.

Specification of Letters Patent. I Patented Feb. 22, 1921.

Application filed May 11, 1920.- Serial No. 380,510.

To all whom it may concern Be it known that 1, J OHN Senses, a citizen er the United States, residing at Holyoke, Hampden county, State of hilassachusetts, have invented certain new and useful Improvements in Loose-Leaf Binders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

This invention relates to certain new and useful improvements in a loose leat binder and more particularly to the ring type of binder wherein the binder ring has interlocking ends held normally operative by the inher nt lateral resiliency or twisting.

The invention has for its primary object to provide quick attachable and detachable rings whereby the rings can readily be disengaged from the cover with the filler and the latter tiled away, being retained intact by the rings.

Further the invention resides in. an improved and economical construction consisting of the features, arrangements and combinations of parts hereinafter described and claimed, reference being made to the accompanying drawings, wherein:

Figure 1 is an open plan view of a binder V embodying the present invention;

Fig. 2 is a transverse section therethrough on line 2--2 of Fig. 1;

' Fig. 3 is a fragmentary lengthwise sectional view on line 3-3 of Fig. 1 showing more clearly the construction of the several associated parts;

Fig. i is an open plan view of a binder embodying a modified form of the invention;

Fig. 5' is a transverse sectional view disclosing more clearly the modified construction; and

Fig.6'is a tragmental sectional view of a further modification; and

Fig. 7 is a detailed'pla'n view of its supporting clip.

Referring more in detail to the drawings the cover 1 has secured to its back 2, as by eyelets 3, a plurality of ring mounts or clips 4, each consisting of laterally and oppositely extending resilient wings turned upwardly and inwardly at their extremities to form a cradle or fulcrum supports 5 for the ring 6. These inturned ends are provided with re ceases or "seats 7 to receive the ring, and

intermediate the wings the clip 4 has a centrally located lip or hook 8 which is preterably struck up from the clip body and designed to have the ring engaged therebeneath. The ring here disclosed consists of a section of a helix of U-sectioned Wire to form an inside channel which the hook or lip 8 engages to more securely anchor the ring, as shown in Fig. 3, the ends of the ring being designed to spring into interlockingrelation.

In Figs. aand 5, a long back plate 9 is provided in lieu of the clips 4 of the preferred form, said back plate 9 being secured at intervals to the back ot' the cover as by eyelets 1:0. Centrally, the back plate is formed with a longitudinal rib 11 interrupted at intervals by cut-outs or notches 12 into which hooks or lips 13 extend from the rib .at one side. The longitudinal side edges of the backplate are rolled inwardly to provide resilient fulcrum support for the rlngs, said edges being also formed withring seats 14: opposite the notches 12.

In practice, when it becomes necessary to replace the'filler with a i'resh or new one,

' the binder rings 6 are pressed downwardly to bring the lower arcs clear of the anchor- 1ng llps and then by rocking the rings latorally on their seats 7, which yield and spread under the added pressure, said lower arcs will swing from beneath the lips and free the rings so that the filler may then be removed with the rings attached thereto. Thus, the rings will be filed away with the tiller and serve as apermanent binder therefor to keep the sheets in order. New rings are secured to thecover by simply engaging the rings in their yieldable seats, pressing downwardly onthe rings at an angle and then swinging them to an upright position for engaging their lower arcs beneath the anchoring lips.

Figs. 6 and 7 disclose a further modification wherein the lips 15 are disposed in the resilient seats 16 of the clip 17, the latter having a raised central rib 18 transversely slotted at 19 to receive the binder ring'20 and hold it upright. The periphery of the ring is formed with spaced holes 21 in which the lips or teats 15'are designed to engage.

one side is entered in an aperture in the ring and pressure then applied to the latter which will effect a spreading of the ring seats until the cooperating teat enters its corresponding aperture.

From the foregoing it will be noted that a binder is provided in which the binder rings are quickly attachable anddetachable from the cover so that the user of the book can disengage the rings from the cover and file away the entire filler mounted on the rings. Since the rings are produced and obtained at a very small cost the cover can readily be equipped with a new set of rings for refilling. The construction is therefore economical, can be manufactured at a very low cost, and will lend itself to any desired spacing of rings as one may wish, requiring more or less spacing of the clips and ring seats. The clips may be made separate, as indicated n Fig. 1, or connected, as in Fig. l, and their shape and design varied without departing from the spirit of the invention. To open the particular form of binder ring it is merely necessary to pull the interlocking ends apart to one side and then permit them to spread apart in the opposite direction through the inherent twisting resiliency.

From Figs. 1 and a it will be observed that the anchoring lips at one end of the cover back are arranged reversely to those at the opposite end thereby necessitating the rocking of the end rings in opposite directions to disengage them from the clips.

By making the rings and clips separate, the shipment of the goods is greatly facilitated because the covers can be spread out and packed together flat, and the rings can be sent separately, thus greatly decreasing the bulk and expense in shipping.

The same cover and clips may be used for different sizes of rings. The user may use a small size ring and if he discovers that he rapidly fills the rings he can remove them and file them away with the loose leaves contained on the rings and then substitute larger rings, or, in a three or four ring binder, he can have the two end rings of a larger size, as for instance, for holding certain loose leaves, and have the intermediate rings of a smaller size for holding memoranda or other slips, the two sets being ontirely separate. The two different sized fillers threaded on the rings can then be removed and filed away separately. This plural filler arrangement has never been accomplished before in the loose leaf binder art.

In all three forms it will be noted that the lateral, resilient portions are resilient and yield so as to permit the lips or teats to engage the ring and thereby maintain the seats under tension and the rings operative. Also, the hooks or lips serve to support the rings against rocking in their seats.

What is claimed is:

1. In a loose leaf binder, a'ring supporting plate having spaced and yieldable ring engaging parts, and a detachable ring lock between the parts.

2. In a loose leaf binder of the ring type a cover, means carried by the cover of the binder for engagement by the binder rings, consisting of a resilient ring support and means engageable by the ring upon placing the support under tension.

In a loose leaf binder of the ring type a cover, means carried by the cover of the I binder for engagement by the binder rings, consisting of spaced resilient'ringsupports and means in each for engagement by the ring upon subjecting the supports to tension to holdthe supports under tension and the ring operative.

l. Ina loose leaf binder of the ring type, means carried by the cover of the binder for engagement by the binder rings, consisting of a resilient ring support and means normally inaccessible by a ring but engage able thereby upon subjecting the support to tension for anchoring the ring.

5. In a loose leaf binder of the ring type, means carried by the cover of the binder for engagement by the binder rings, consisting of a sheet metal body provided with oppositely disposed resilient ring supports, and an interposed ring anchor.

6. In a loose leaf binder of'the ring type, means carried by the cover of thebinder for engagement by the binder rings, consisting of a sheet metal body provided With oppositely disposed resilient ring supports, and an interposed ring anchor engageable by a ring only upon placing the supports under tension.

7. In a loose leaf binder of the, ring type, means carried by the cover of the binder for engagement by the binder rings, consisting of a clip secured to the back of the cover and having laterally disposed resilient portions providing spaced ring seats, and means for anchoring a ring thereto.

8. In a loose leaf binder of the ring type, means carried by the cover of the binder for engagement by the binder rings, consisting of a clip secured to the back of the cover and having laterally disposed resilient portions providing spaced ring seats, and an intermediate anchoring lip struck up from theclip body. 7

9. In a loose leaf binder of the ring type, means carried by the cover of the binder for engagement by the binder rings, consisting of a clip secured to the back of the cover and having laterally disposed resilient portions providing spaced ring seats, and means for holding a ring upright on the supports.

In testimony whereof I affix my signature.

JOHN SCHADE.
